Abstract

The estimation of carrier frequency of communication signals with high estimation precision and wide estimation range is required in lots of applications. A carrier frequency estimation algorithm based on maximum-likelihood principle and iterative process with high precision and wide estimation range is proposed in this paper. The performance of the iterative algorithm is compared with the other two widely used classic carrier frequency estimation algorithms by computer simulations. In simulation results, the iterative algorithm has better performance than the others´.
